The dependency jars are not part of the source branch or
awapi_java_lib_2.1.0.tar.gz. All dependencies are located in a
separate download file, which now excludes j2ee jar (
http://google-api-
adwords-java.googlecode.com/files/includelib_jars_0808.tar.gz). Most
likely, you still have this jar in your local project. Once you
remove it, the build.xml won't include it as part of the build
process.
